Shipping and Returns
Once an order is placed we are no longer able to make changes to content or shipping service level. Once items are shipped with the specified carrier Riffraff Diesel Performance© is not liable for late, lost, stolen, or damaged goods in transit or after delivery. UPS Transit time can vary based on service selected from 1-8 business days. USPS Transit times can vary from 2-10 business days depending on which service is selected. USPS Shipping is not a guaranteed service, and is not able to be refunded based on a delivery/ transit delay. Unless the customer requests Signature Required at checkout in the comment box, which is provided on request free of charge, we are unable to make a claim with the carrier for missing parcels. Riffraff Diesel reserves the right to require a signature on orders over $500. Next Day Air, and Expedited Services cut off time for ordering is 12pm PST, and can change without notice due to unforeseen circumstances, contact us if you have questions. Free Shipping service used is UPS Ground unless other than specified. At this time Saturday Delivery is only available upon request, and only on Friday Next Day Air shipments, per UPS guidelines. Please be advised, carriers only count business days as transit time, not weekends or holidays. Standard shipping pick up and delivery days are Monday through Friday, but do not include observed holidays and company closures. We reserve the right to use the carrier of our choice if we determine it provides the customer with better service. If an order is refused and shipped back without shipper authorization the customer will be charged for the return shipment cost.
